Here in the states, it looks like we'll be seeing Gran Turismo 5 Prologue a few weeks later than the UK and Europe.

Quote:

"Gran Turismo 5 Prologue will be out on in UK and Europe on March 27 as a download on PSN - more than three weeks ahead of the US.

March 28 will see the release of the Blu-ray version of the game, which you'll be able to pick up play off the disc like any other game. The downloadable PSN version will arrive a day earlier on March 27."

They're fine. I actually prefer an always connected experience.
I'd really prefer an offline way to play, but its not a bother.
I don't really like them, and am more reluctant to buy a game because of it.
I won't buy them. I want my games offline.
